Aero Helmet testing
Well it's officially complete.
I conducted a little research into the effectiveness of Aero Helmets using a GPS tracking device and Durance hill a few weeks ago. The data has been analyzed and used to preform calculations to find the coefficient of drag. The coefficient number was turned into a number for Power (in Watts) and the results are displayed above.
Basically a 150 Watt output from a cyclist will maintain between 30 and 36 km/hr depending on a helmet selection. Race wheel aerodynamics are far superior to any helmet someone straps on their head.
My testing has it's own set of flaws. I wouldn't say that these numbers are 100% accurate, but I stand by my testing. Let me know you would like to know more.
